NOAA has operationalized SOLAR-1 at Lagrange Point 1 (L1) to serve as the nation's premier space weather early warning system. Complementing India’s Aditya-L1, it tracks Coronal Mass Ejections (CMEs) and solar wind in real-time to protect global power grids, GPS, and satellites.
Click to View MoreCoronal Mass Ejections are massive eruptions of magnetized plasma from the Sun’s corona that can travel through space and impact Earth. They are caused by magnetic instabilities and reconnection in the solar atmosphere. CMEs can trigger geomagnetic storms, auroras, satellite disruptions, and power grid failures. Studying them is crucial for space-weather forecasting, protecting technology, astronaut safety, and understanding planetary habitability. Recent observations, including the first CME detected on a red dwarf star, highlight their significance for both solar physics and exoplanet research.
